Inheritance Features of Mating Behavior Components in <Emphasis Type="Italic">Drosophila melanogaster</Emphasis> and Their Significance for Fitness

Components of mating behavior of Drosophila melanogaster mutant and wild-type strains were studied with respect to fitness. The magnitude of the effect of genotype on the male mating activity, female sexual receptivity, fertility and viability was determined. Strong positive correlation was found between the male mating activity and fitness components. It was shown that mating of strains contrasting in sexual behavior features can be accompanied by both heterosis and maternal effect. Inheritance coefficients were determined for sexual behavior components.__________Translated from Genetika, Vol. 41, No. 5, 2005, pp. 614–619.Original Russian Text Copyright © 2005 by Volkova, Vorobjova.
